l Application filed May 5, 1902. Serial No. 105,932.Y (No model.)

To aZZu/towt it mfcty'con/cern;

Be it known that I, WILLIAM VORDEM- FELDE, a citizen of the United States, residing in the city of St. Louis, in theState of Missouri, have invented certain Vnew and useful Improvements in Sliding-Door Fasteners, ofV which the following is a full, clear, and exact l ing throw-arm 9, that extends over the opendescrption, reference being had to the accompanying drawings, forming part of this specifcation.

My invention relates to sliding-door fasteners, more particularly for use upon double doors of street-railway cars.

,My invention consistsin features of novelty hereinafter fully des'cribed,and pointed out in the claim. f

Figure I is a vertical section of my fastener with the catches thereof shown in engaged position. Fig. II is a vertical Section taken on line II II through one-half ofthe fastener. Fig. III is a horizontal transverse section taken on line III III, Fig. I. Fig. IV is an elevation of the door-handle.l

A A designate fragments of two doors-adapt.

ed to be united by my fastener and in which mortises are made to receive the casings.

1 l designate the casings Set into the facing edges of the two doors to be connected by the latch and inthe side walls of which are openings 2 2.

3 3 are swing-catches mounted on pivot-` stems 4 4, carried by the casngs 1 l and The swing-catches are provided with hook-arms 5 5, that are adapted to engage each other, as Seen in Fig. I, when the doors are brought together. The hook-arms are provided with shoulders 6 G, andwithin the casings are bow-springs 7 7, that tend to hold the hook-A arms in the path of movement of each other that occurs when the doors are brought together.

8 8 are stop-pins in thecasingsl l, that limit the vmovement of the hook-arms 5 5, that is imparted thereto by the springs 7 7, The hook on the arm 5 is projected downwardly and that on the arm 5 is projected upwardly, and the spring 7, that bears against the rst-named arm, is located above thehook# arm, and the spring that bears against the hook-arm 5 is located below it, so as to cause the arms to be heldtoward each other for engagement.

The swing-catch 3 has an upwardly-extending 2 in the casing 1, and the swing-catch 3 has a downwardly-,extending throw-arm, that extends over the opening 2 in thecasing l,

lO 10 designate sockets Xed to the faces of the doors, and 11 ll`a're soeketplates also fixed to the faces of the doors and in line with the sockets referred to. The socket-plates are provided with apertures, as shown at ll2, Figs. II, III, and IV, that register with apertures extending through the door into communication with the openin gs 2 2 in the latchcasings.

v13 13 areboWLshaped handles, the arms of which are furnished with pins 14 14, that are 'seated Vin the Sockets 10 10 and .the sockets of the socket-plates l1 1l. The handle 13 is provided with a finger 15, that passes through the aperture in the Socketfplate Il and the openings 2 in the, casing and bears against the :throw-arm 9 of the swing-catch`3, from which it will be seen that by swinging the handle 13 laterally Said finger will be caused f to exert .apressure against the throw-arm 9 to carry the hook-arm 5 of the swing-catch 3 out of engagement with the hook-arniof the Swing-catch 3. The handle 13 is provided with a nger 15, extending inwardly from its lower arm to bear against the throw-arm 9 of thesWIng-catch 3, so that upon a swinging. movement being imparted to the handle the hook-arm 5 will be raised out of engagement with the hook-arm 5,; the operation being similar to that in moving the hookarm 5, as before stated, except that in one movement one hook-arm is thrown downwardly and in the other Inovementtheother hook-arm is thrown upwardly.

I claim as my invention- The combination of a pair of easngs, eorl bow-springs each engaging at one end in a responding hook-arms swingngly mounted corner of said easing and at the other end in the casings, throw-arms carried by said with said hook-arms.

hook-arms, a. swngingly mounted handle WM. VORDEMFELDE. 5 mounted in each casing, fingers carried by In presence ofsaid handles and adapted to bear against said H. F. VOGEL, f

throwa1ms, shoulders on said hook-arms, and M. H. MURPHY.
